Played using the Sicilian Defense, Kan Variation, the game culminated in a remarkable zugzwang position, showcasing Fischer's early mastery.

Game Context

The Mar del Plata 1959 tournament was a significant event in Fischer's career, marking his rise as a global chess prodigy. His performance, including this game against Rossetto, was part of what enthusiasts call his "Argentinian Triangle," alongside victories against Pilnik and Shocron. The game was recognized as the Game of the Day on November 2, 2009, by ChessGames.com, highlighting its enduring appeal.

Opening: Sicilian Defense, Kan Variation

The game opened with the Sicilian Defense, specifically the Kan Variation with the Maroczy Bind Reti Variation (B41):
1.e4 c5
2.Nf3 e6
3.d4 cxd4
4.Nxd4 a6
5.c4 Qc7
6.Nc3 Nf6
7.Bd3 Nc6
8.Be3 Nxd4
9.Bxd4 Bc5
10.Bc2 d6
11.O-O Bd7

This opening is known for its solid structure, offering Black counterattacking chances. Fischer, playing White, employed the Maroczy Bind (c4), aiming to control the center and restrict Black's pawn breaks. By move 11, Fischer had castled, setting up a flexible position for the middlegame.

Middlegame: Fischer's Strategic Breakthrough

The middlegame saw Fischer assert his dominance through precise moves. A pivotal moment came on move 19:

19. Nd5!

This move, described as resourceful in annotations, created significant problems for Black. Fischer noted in My 60 Memorable Games that this move aimed for a "big breakthrough on c5." Rossetto responded with 19...Bxd5 20.exd5 e5, leading to a complex position where Fischer maintained control.

Another critical juncture was Black's 23...f5, which Fischer identified as a decisive mistake. He suggested 23...a5 as a better alternative, as 23...f5 weakened Black's pawn structure, allowing Fischer to exploit the queenside. The sequence continued:

23. Rd3 f5
24. Ra3 Nb8

Here, 24...Nb8 trapped Black's knight, setting the stage for Fischer's endgame strategy.

Endgame: Zugzwang Triumph

The endgame showcased Fischer's ability to convert advantages into a win. After:

25. c5 bxc5
26. bxc5 dxc5
27. Rxc5

White gained a strong passed pawn on d5. Fischer's play from move 17 onward was described as "practical perfection" in analysis, as he methodically increased pressure. The game reached a zugzwang position, where Black had no viable moves. By move 37:

36. g4 fxg4
37. hxg4 1-0

Black resigned, as White's pawns were unstoppable, and Black's pieces were immobilized. The final position was described as "astonishing" in commentary, with Black unable to move without conceding defeat.

Significance

This game is a cornerstone of Fischer's legacy, illustrating his ability to weave complex strategic ideas, such as zugzwang, into practical play. Its inclusion in My 60 Memorable Games and its recognition as a Game of the Day underscore its historical importance. The game also highlights Fischer's dominance in the Mar del Plata tournament, a stepping stone in his journey to becoming a world champion.
